Study Type:	Interventional
Study Design:	Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment
Condition:	Major Depressive Disorder
Interventions:	Drug: Escitalopram Drug: Placebo

Participant Flow

Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment period was from April 1, 2005 through March, 2007 at 40 centers in the US.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
2 week screening with one-week single-blind placebo. Patients meeting selection criteria at baseline were randomized to once daily escitalopram 10-20mg/day or placebo (1:1).

Reporting Groups

	Description
Escitalopram	Once daily oral administration of escitalopram tablets - 1 tablet (10mg) for the first three weeks, then 1 tablet (10mg or 20mg) depending on therapeutic response and tolerability.
Placebo	Once daily oral administration of placebo tablets

Hide Outcome Measure 3

Measure Type	Other Pre-specified
Measure Title	Children's Global Assessment Scale
Measure Description	Change from baseline to week 8 in CGAS score which rates the patient's general level of functioning for the past 14 days on a scale of 1 (most impaired) to 100 (healthiest).
Time Frame	At baseline and end of week 8
Safety Issue	No

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The Intent-To-Treat Population was used. The Last Observation Carried Forward (LOCF) technique was used to impute missing data.

Reporting Groups

	Description
Escitalopram	Once daily oral administration of escitalopram tablets - 1 tablet (10mg) for the first three weeks, then 1 tablet (10mg or 20mg) depending on therapeutic response and tolerability.
Placebo	Once daily oral administration of placebo tablets

	ANCOVA on the Change from Baseline to Week 8 in CGAS score. The model included treatment and center as factors and baseline score as covariate. Missing values were imputed using the LOCF approach.
